IMPROVEMENT IN SULKY-PLWS.

Specification forming part of Letters Patent No. 152,73 l, dated July 7, 1874 application filed March 13, 1874.

To all whom it may concern:

Be it known that I, NORMAN DU Bois, of Greenville, county of Darke and State of Ohio, have invented certain Improvements in Breaking Sulky-Plows, of which the following is a specification:

My invention relates to an arrangement of hand-levers, whereby the operator may govern the depth of the plow or raise it entirely ont ofthe ground without leaving his seat, the entire management of the team and plow being from the drivers seat, as hereinafter fully described.

Figure l is a perspective viewvof the entire machine, except a part of one wheel. Fig. 2 is a side elevation of the mechanism for governing the depth ofthe plow. Fig. 3 is a top view of the apparatus which clamps and holds in position the plow-beam. Fig. 4 is a view of the clamp and nut which holds the plate B in position when properly adjusted. Fig. 5 is a view of the plow-beam as attached to the sulky.

A and A' are the wheels, 'A' being larger than A for the purpose of runnin g in the furrow. B is the plate to which the plow-beam is attached. C is the axle; D, the lever for governing the depth ofthe plow; E, the lever i'or throwing the plow out of the ground, L is the drivers seat, and I a foot-board; J, the tongue of the sulliy. The manner of attaching and adjusting the plowbeam is shown in Figs. 3 and 5. The beam is placed upon the plate B, having the slots T', the bolts O' being passed through the slots. The clamps lV are placed upon the bolts and upon the top of the plow-beam. The adjusting-loops C', Fig. 4, pass around the shat't C and through the stops K', and are held in place by the` nut E'. These loops are split through, as shown in Fig. 4, to allow them to be drawn tightly around the shaft or axle O, and hold iirmly the stops K', which stops govern the adjustment of plate B sidewise, said plate turning loosely on the axle O. The slots T' in plate B also give additional adjustment to the beam of the plow. The adjustment of plate B sidewise is t'or the purpose oit' giving the screw-nuts N and O at its ends.

more or less land, according to circumstances, when two or three horses are used.` The arm F' is attached to the axle of the sulky, and strikes against the stud-pin b, which pin is attached to the lever D, and serves also as the fnlcrum of the pawl U, which pawl is operated by the rod l-I and latch F, Fig. l.

The toothed arc T is attached to the houndsV K, which are attached to the tongue J. then the lever D is thrown forward, as shown in Fig. 2, the pin b strikes against arm F', and holds the plow at a less depth in the ground 5 but when it is desired for the plow to run deeper, the lever D is thrown back, and consequently the plow goes deeper into the ground. The channeled arc P is also attached to the axle C at the opposite side from the toothed are T, this are P being operated through the lever E and chain M, the length of this chain being adjustable through The object of thisarrangement is to -raise the plow out ot' the ground independent of the arc T and pawl U, the arcs l? and T, with their respective attachments, operating entirely independento` each other; and in case ot' the point of the plow striking a stone or other obstruction, the axle will rise with the plow independently of both arcs, and without dis turbing any other part of the sulky. Thus it will be seen that the plow is confined in the direction of the draft. Yet when the plow strikes an obstruction it can rise without giving an upward motion to any part of the snlky but the axle, which has free play npward when meeting any obstruction. The plow is raised out of the ground by means of the lever E, the foot Q of which pulls upon the chain M when the lever is thrown backward. ll'hen the plow is raised, the pawl It drops over the pin S, and holds it out of the ground. When it is desired to lower the plow, the pawl R is raised oit' the pin S by means of the latch G and rod H. lVhen the plow is in motion the chain M is slack, there heilig no tension on it, except in raising the plow out ot' the ground. 4 The curved i'oot Q of the lever E falls -in under the front end of arc P, when the lever is thrown forward and takes up the chain and keeps it out of the way ofthe pawl R. When the plow is raised substantially as shown and described, for the purposes specified.

2. The toothed are T and lever D, having.

stud b attached to the hound K, in combination with the arm F', attached to the axle C, and with arc P, chain M, and lever E, substantially as shown and described.
